Description
This block generates an Integer output signal by using a table.The time points and y-values are stored in a matrixtable[i,j], where the first column table[:,1] contains theReal time points and the second column contains the Integer value of theoutput y at this time point.The table interpolation has the following properties:
- An assert is triggered, if no table values are provided, if the time points are not strict monotonically increasing, or if the second column of the table matrix does not contain Integer values.
- Values outside of the table range, are computed by extrapolation according to the setting of parameter extrapolation:
extrapolation = 1: Hold the first or last value of the table, if outside of the table scope. = 2: Extrapolate by using the derivative at the first/last table points if outside of the table scope. (This setting is not suitable and triggers an assert.) = 3: Periodically repeat the table data (periodical function). = 4: No extrapolation, i.e. extrapolation triggers an error
- If the table has only one row, no interpolation is performed and the table values of this row are just returned.
- Via parameter shiftTime the curve defined by the table can be shifted in time. The time instants stored in the table are therefore relative to shiftTime.
- If time < startTime, no interpolation is performed and zero is used as ordinate value for the output.
Example:
table = [ 0, 1; 1, 4; 1.5, 5; 2, 6];
results in the following output:
